Light emitting assemblies include at least one light source and at least
one film, sheet, plate or substrate having optical elements or
deformities of well defined shape on at least one surface that have
reflective or refractive surfaces for controlling the light output ray
angle distribution of the emitted light. The film, sheet, plate or
substrate may be positioned near the light emitting surface of a light
emitting panel member with an air gap therebetween or over a cavity or
recess in a tray through which light from a light source in the cavity or
recess is emitted.
